3 Claims. (Cl. 24 -74).-

This inyentionrelatesto buckles and more par:

ticularly to a double.adjustableslocking.bucklehavingsat-each endameans-for clamping a strap or belt.

This invention is arr-improvement on applicants former patent, No.2,430,928November 18, 194 .7.- -Applicants patent showsa buckle attachedto. one end of-a strap-Land having 'at its opposite: end-a .clampinrdevice adaptedrto coact with afabric or. cloth such- .-for exampleasthe top ofa stocking.

One; of the; objects, of-;the.gpresen-tinvention is to provide a buckle-formedofra -single'pieee of;

Another object of this inyention;is to provide a same may be;conveniently carried.

A further-object; is toprovide. a buckle OfllhG above character whichwill be reliable and efiicientin use and .operation and dependable inthat it will not release the fabric until manipulated withthatiintention...v

Referring to the drawings in detail and more particularly to Figure l,the buckle is illustrated as gripping a cloth band at each end. Thebuckle is made from a continuous piece of wire of the proper resiliencyand flexibility to permit its easily being manipulated withoutdistortion. The wire starts at the joint I, extends upwardly and thentransversely across the top of the buckle at 2 thence downwardly at 3 tothe lower side l, thence upwardly at 5 then again transversely acrossthe top of the buckle at 6, thence downward'ly at],thence:transversely.acrossztheabote tom;- of the buckle at 1.8land;thence upwardly :to.

the joint"! It will'beobserved that the buckle. ispprovided with fourshoulders'or projecting portions-9,; I5 1.

atthetopof the buckles and-H, I2 at the bottom.

Thesewshoulders are necessary torassure a .firm.

gripping of the strap. as .willbexexplained.

In attaching 'the strap to the. upper portion 01' the buckle, the buckleis held in the handin the position'shownzin;liig.'.:2, the-strap'tend i3is .then

passed downward-1y betweenrtheprojectingzxpore tions 9 and/IE!thence'under and over. portion-"2 thence-between: the portion 2 and-theportion 5.

. The strap. is then -.drawn'1tothe-desired position and locked.Icy-oscillating. the clamp. or .oscillator.

When in'lockedrposition the arms 9 and I0bear;against:the.iverticalizportions::3 andari as clearly 'shown inFig.2 11.

Likewise in attaching. .the. strap..t0 the lower portion orthe .buckle,the strap end .l 4 'is' passed downwardly between :the projectingvportions I i andtl 2 inrth'e vposition shown:v -ini:Fig. .2 Ithenceunder and. over -portion 8, .thence between the portion. 8 and the:portion :4. .11

The strap is then drawn tothe:desiredposition andlocked by. oscillatingtheclamp or oscillator formed-ybythe' parts. I l 4 and-IZ'Jas-indic'ated by dotted lines in Fig. 2 and threading .the same.

through ithej loop formed .byrsides .r'l Ii ini-the- .position shown. inFig.1."v

When in locked: positionsthe armsz'or. .projec tions .I hand [2 bearagainst thexverticalportions;

1 and I aszshown: in Fig. 1.

As clearly illustrated, the projecting portions 9, Ill, H and I2 in Fig.2 all appear on the upper surface of the buckle before the strap endsare attached and after the strap ends are attached and locked, theprojecting portions 9, H], H and I2 appear on the lower surface of thebuckle bearing against the vertical portions l, 3 and 1 as abovedescribed and as shown in Fig. 1.

Thus in order to securely lock the strap l3 after it is drawn to thedesired position one of the loops is made shorter and narrower at theside and wider at the free ends than the other, the wide portions ofsaid loop forming shoulders or projections 9 and I0. These shoulders orprojections and their connecting portion 6 comprise an oscillator whichis first oscillated to one side and then to the other side therebyshifting it through the adjacent loop into locked position as shown inFig. 1. In this position the shoulders or projections 9 and I appear .onthe opposite side of the vertical portions 3 and l to that shown in Fig.2.

To securely lock the strap after it is drawn to the desired position,the oscillator formed by the projections I I and I2 and their connectingportion 4 is first oscillated to one side and then to the other sidethereby shifting it through the adjacent loop into locked position asalso shown in Fig. 1. Likewise in this position the shoulders orprojections appear on the opposite side of the vertical portions 3 and lto that shown in Fig. 2.

The modification shown in Fig. 4 shows a larger device provided with ahandle I5 at one end and means for gripping a bag I6 or like article tobe carried. The device is constructed of a single piece of heavy,resilient wire. The wire starts at the joint H passes upwardly and thentransversely across the top as at I8, thence downwardly as at l9, thencetransversely across the bottom as at 20, thence upwardly as at 21,thence transversely across the top as at 22, downwardly as at 23, thencetransversely across the bottom as at 25 and thence upwardly to the joint[1.

To firmly attach the handle to the bag, the end portion of the bag isfolded then passed in an upward direction adjacent the bar 24, thenceover the bar 24 and drawn downwardly beneath the bar 20.

It will be observed that this device is provided with shoulders orprojecting portions 25, 26. These shoulders are 'bent inwardly towardthe side, portions I9 and 2| and the bar is also bent relative to theside portions 19 and 2| in the same direction as the shoulders are bent.

The bending inwardly of the bar 20 above described effects a sharperturn of the flexible material which is gripped and. thereby increasesthe pressure of the body of the material against the adjacent endportion thereby increasing the frictional force between the adjacentsurfaces preventing the disengagement thereof.

As shown in Fig. 4, to securely lock the bag l6 after it is drawn to thedesired position, the oscillator formed by the projecting portions and2B and their connecting portion 24 is first oscillated to one side andthen to the other side thereby shifting it through the adjacent loopinto locked position as shown in Fig. 4. In this position the projectingportions 25 and 26 appear in front of the portions 2| and IS.

The device being constructed of heavy, resilient Wire and the shoulders25, 26 and the wire 20 being bent in the manner described, the top ofthe bag or like article is securely locked to the handle as clearlyillustrated in Fig. 5 of the drawing.

While I have herein shown and described only certain specificembodiments of my invention and have set forth only certain possiblemodifications, it will be appreciated that changes and variations can beresorted to without departing from the spirit and scope of my invention.

I claim:

1. A device of the character described consisting of a continuous lengthof resilient wire-like material joined at the ends presenting twoadjacent elongated loops having adjacent end portions at one extremityto engage opposite sides of flat sheet like material loopedtherethrough, a tube like handle encasing the opposite end portion ofsaid loops, one of said loops being shorter and narrower at the sidesand wider at the free end than the other, the wide portion of said loopforming shoulders or projections, said shoulders or projections beingoffset or bent inwardly toward the longer loop whereby the fiat sheetlike material is securely held against withdrawal when tension isapplied thereto.

2. In a device of the character described in claim 1, wherein the lowerportion of the longer loop is also bent inwardly relative to the sideportions of said loop.

3. A device of the character described consisting of a continuous lengthof resilient wirelike material joined at the ends, presenting twoadjacent elongated loops having adjacent end portions at one extremityto engage opposite sides of flat sheet like material loopedtherethrough, one of said loops being shorter and narrower at the sidesand wider at said extremity than the other loop the wide portion of saidone loop forming shoulders or projections said shoulders or projectionsbeing offset or bent inwardly toward the longer loop, said extremity ofthe longer loop also being bent relative to the side portions of saidlonger loop in the same direction as the shoulders are bent whereby theflat sheet like material is securely held against withdrawal whentension is applied thereto.
